Isaiah 51:9 · KJV


Context

7

Hearken unto me, ye that know righteousness, the people in whose heart is my law; fear ye not the reproach of men, neither be ye afraid of their revilings.

8

For the moth shall eat them up like a garment, and the worm shall eat them like wool: but my righteousness shall be for ever, and my salvation from generation to generation.

9

Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon?

10

Art thou not it which hath dried the sea, the waters of the great deep; that hath made the depths of the sea a way for the ransomed to pass over?

11

Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.


Commentary

KJV Study Commentary
The prayer 'Awake, awake, put on strength, O arm of the LORD' uses anthropomorphic language depicting God as needing arousal - actually expressing urgent longing for deliverance. The reference to 'ancient days' and 'Rahab' (Egypt, per Psalm 87:4) recalls Exodus deliverance, establishing precedent for present request. This models prayer grounded in rehearsing God's past mighty acts as basis for confidence in future intervention.

Historical & Cultural Context

The 'arm of the LORD' crushed Egypt at the Red Sea and will be revealed in Christ (53:1). This prayer from exile anticipates a new exodus through return from Babylon, ultimately fulfilled in Christ delivering from sin and death.
